Instructions
Determine the amount of depreciation expense for the years ended December 31, Year 1, Year 2, Year 3, and Year 4, by (a) the straight-line method, (b) the units-of-activity method, and (c) the double-declining-balance method.
Answer:
a. Straight-line method:
Year 1: [($108,000 – $7,200) ÷ 3] × 3 ÷ 12....................................... $ 8,400
Year 2: [($108,000 – $7,200) ÷ 3]................................................... 33,600
Year 3: [($108,000 – $7,200) ÷ 3]................................................... 33,600
Year 4: [($108,000 – $7,200) ÷ 3] × 9 ÷ 12....................................... 25,200
b. Units-of-activity method:
Activity rate = ($108,000 – $7,200) ÷ 12,000 hours = $8.40 per hour
Year 1: 1,350 hours × $8.40......................................................... $11,340
Year 2: 4,200 hours × $8.40......................................................... 35,280
Year 3: 3,650 hours × $8.40......................................................... 30,660
Year 4: 2,800 hours × $8.40......................................................... 23,520
c. Double-declining-balance method:
Year 1: $108,000 × 2 ÷ 3 × 3 ÷ 12................................................... $18,000
Year 2: ($108,000 – $18,000) × 2 ÷ 3............................................. 60,000
Year 3: ($108,000 – $18,000 – $60,000) × 2 ÷ 3................................. 20,000
Year 4: ($108,000 – $18,000 – $60,000 – $20,000 – $7,200)............... 2,800
Note: Book value should not be reduced below $7,200, the residual value.
